The Fed-4 were produced in two versions. The first model (reffered to as Fed-4 (a)) has wind knob and was modified from Fed-3 (a) to accept a light meter. The Fed-4 (b) has much higher viewfinder assembly to add a light meter. The light meter control knob is where the rewind knob was so the rewind knob now sticks out of the side. The Fed-4 (b) camera again was available with either single or dual lettering [2].

Although soviet camera industry produced a lot of commemorative cameras, only very few Fed's were among them. That's why an anniversary Feds becoming very scarce nowadays. To commemorate the "Great October-50" Fed issued three cameras: Fed-3b, Fed-4b and Fed-11 Atlas with special engravings. 

Beside this, the limited quantity of Fed-2 and Fed-3 cameras entered the market without "Great October-50" engravings, but with special anniversary boxes and "67" date prefixes in their serial numbers (both body and lens).

Although mass-market Fed cameras have no date prefix in their serial numbers, the commemorative Feds have special date prefixes "67"  both on camera body and Industar-61 lens.
